Question about 2005 Dodge Ram 2500 Truck
The code tells me that the pressure sensor volts are to high and its the 2nd time this has happened. I'm I going to have to replace this sensor and is it easy to replace? I don't even know where it's at. Thanks guys... Chad

I replaced the EGR Valve ($80 after tax), problem solved, vanruns great now. Now my problem is that I can't get the light to turn off.

dont know lots about this witout engine size but some have 1 coil per cylender possible coil is bad or plug 02 sensor will cause some problems but a miss fire will cause it to run like trash

I would disconnect the battery for about 3 mins. Then drive it around tell the light comes on and then check the codes again by cycling the key 3 times. Have you put new plugs in? I have replaced my plugs 4 times tell I relized Dodge durango 4.7 and Magnums do not like platnium plugs. They will miss almost from the first time putting them in. Then I would go to Cylinder 3 and look at the plug. For the most part its either plugs on the left bank or Coils. all you have to do is pull the coil put the plug from that cylinder in the coil and ground the electrode out. If it sparks the coil is working if not then change the plug if it still dosnt you have a bad coil. The power steering switch is somthing way diffrent. The o2 sensor smells the gas and tells the computer wether its needs to back off on fuel or put in more. So if thats bad youll lose about 2 miles per gallon if you need more help go to http://www.dodgetalk.com/forums
They have always helped me or email me at firstname.lastname@example.org I hope this helps.

Sorry I had company show up & couldn't get back until this am.
On yours, you leave connector on at TPS, and with key on, not running, use voltmeter at center terminal. At idle it should read more than 200MV. At wide open throttle (WOT) should be less than 4.8 volts. Also should increase gradually as you open throttle, any drop off, or large fluctuation indicates problem, as long as your smooth doing it. If not within these voltages, or jumps up & down, drops off, replace it. You still should be able to do same with ohmmeter & harness disconnected, and connected at 2 of the pins at sensor. (it's a potentiometer) Increase & decrease same rules & smooth. If doesn't work at one set of pins try different combinations, or ground & one pin.One way or another you should find the right combination to get a reading in ohms.

One of 3 things can cause this behavior of the oil pressure light going on and off: (1) oil level might be a little low... double check and make sure your oil is porperly topped off; (2) sensor is defective... which might require replacement; (3) oil pump problem... this can be an obstruction of some kind of the oil pump. If there is a strainer, which is typical, there might be sludge or something else obstructing the entry to the oil pump, thus, resulting in lower pressure output. It is rare, not impossible, for the oil pump itself to be defective... but again, very rare. If the issue is at the oil pump, it willmost commonly be an obstruction. Try having the engine flushed professionally. There are auto service centers with this capability. It is probably the most affordable first step to take. If after a flush the problem persists, then have the sensor checked.

Evaporative Emissions Control System Pressure Sensor High Input
What does that mean?
The EVAP (Evaporative Emissions) System allows fuel tank vapors to be purged into the engine and burnt rather than expelled into the atmosphere as harmful emissions. The EVAP system contains a pressure sensor to check the integrity of the system. Periodically, the EVAP system performs a pressure test to check that there are no leaks in the system. It uses this sensor, also known as a fuel tank pressure (FTP) sensor to check for leaks. Basically P0453 means the PCM (Powertrain Control Module) noticed the EVAP Pressure sensor or FTP is indicating a higher than normal pressure (above 4.5 Volts) in the EVAP system. NOTE: On some vehicles the FTP is a part of the fuel pump assembly in the tank.

There will likely be no noticeable symptoms along with this code other than the MIL (Malfunction Indicator Lamp), commonly known as Check Engine Light illumination. However, there may be noticeable fuel odors in some cases.
A P0453 DTC trouble code may be caused by one or more of the following:
Using an scan tool access FTP sensor value with Key on Engine off (KOEO). Normal value is usually somewhere near 2.5 Volts at atmospheric pressure (may fluctuate some due to altitude). It shouldn't ever be above 4.5 Volts.
1) If it is close to 2.7V with the gas cap off, the problem is likely intermittent. Using a Digital Volt Ohm Meter, measure the voltage on the signal wire while trying to induce the problem by wiggle testing all the wiring at the FTP sensor. If the voltage fluctuates when wiggle testing, check for connector problems; i.e. water in the connector, broken or chafed wiring.
2) If the value shown on the scan tool is above 4.5V, unplug the sensor (if possible) and check for voltage again. If the high voltage is still present when unplugged, inspect wiring harness for a short to voltage on the signal wire. If the high voltage disappears when unplugging the sensor, check for a good ground to the sensor and proper reference voltage. If you have a good ground and 5 Volts reference voltage, replace the FTP sensor since it's likely shorted out.
